RESUMEN

La incidencia del melanoma ha aumentado drásticamente en las últimas décadas y la precisión diagnóstica clínica, por parte de los dermatólogos, se ha estimado en alrededor del 75-80%. El factor pronóstico más importante sigue siendo el grosor tumoral y por ello, es muy importante el diagnóstico precoz del melanoma para la supervivencia de los pacientes afectados. La dermatoscopia o microscopía de epiluminiscencia es una técnica in vivo, no invasiva, que ha abierto una nueva dimensión en la caracterización morfológica de las lesiones cutáneas pigmentadas, pues permite la visualización de estructuras de la epidermis, unión dermo-epidérmica y dermis superficial que son invisibles a ojo desnudo. Numerosos estudios previos han demostrado un aumento en la sensibilidad, especificidad y precisión diagnóstica del melanoma, mediante la dermatoscopia. En la presente revisión, se tratarán los parámetros y patrones dermatoscópicos asociados al melanoma y se describirán los algoritmos diagnósticos más importantes que intentan facilitar el diagnóstico dermatoscópico del melanoma.
